| titleOfInvention | Bisphenol-A and nonylphenol double-template molecularly imprinted polymeric microspheres |
| abstract | The invention relates to bisphenol-A and nonylphenol double-template molecularly imprinted polymeric microspheres. The bisphenol-A and nonylphenol double-template molecularly imprinted polymeric microspheres are prepared by steps of dissolving nonylphenol and bisphenol-A in chloroform, adding methacrylic acid, performing ultrasonic treatment for 30 minutes, and assembling for 8-12 hours at the temperature of 0-4 DEG C; adding water repellent agents, surfactants, ultrapure water, crosslinking agents and initiators and then mixing; performing ultrasonic treatment for 10-15 minutes, leading in nitrogen gas for 8-15 minutes to remove oxygen, then performing ultrasonic treatment for 10-15 minutes again to form stable emulsion, stirring in water bath at the temperature ranging from 50 DEG C to 100 DEG C, reacting for 5-24 hours to obtain white polymeric microspheres; grinding the polymeric microspheres, extracting in solution composed of methanol and acetic acid at the proportion of 9:1 by means of Soxhlet extraction until no nonylphenol or bisphenol-A is detected by ultraviolet ray, eluting with methanol until the solution is neutral, grinding again and screening, precipitating with acetonitrile, and finally drying in vacuum. The molecularly imprinted polymeric microspheres are high in selectivity, high in adsorption capacity, high in extraction recovery rate and uniform in particle size, and are applicable to enrichment and analysis of bisphenol-A and nonylphenol in aquatic products and samples in water environments. |
